The Amiga Portal

The 1987 Amiga 500 was the best-selling model.
Shortcut

Amiga is a family of personal computers introduced by Commodore in 1985. The original model is one of a number of mid-1980s computers with 16- or 16/32-bit processors, 256 KB or more of RAM, mouse-based GUIs, and significantly improved graphics and audio compared to previous 8-bit systems. These systems include the Atari ST—released earlier the same year—as well as the Macintosh and Acorn Archimedes. Based on the Motorola 68000 microprocessor, the Amiga differs from its contemporaries through the inclusion of custom hardware to accelerate graphics and sound, including sprites and a blitter, and a pre-emptive multitasking operating system called AmigaOS.

The Amiga 1000 was released in July 1985, but production problems kept it from becoming widely available until early 1986. The best-selling model, the Amiga 500, was introduced in 1987 along with the more expandable Amiga 2000. The Amiga 3000 was introduced in 1990, followed by the Amiga 500 Plus, and Amiga 600 in March 1992. Finally, the Amiga 1200 and Amiga 4000 were released in late 1992. The Amiga line sold an estimated 4.85 million units.

Although early advertisements cast the computer as an all-purpose business machine, especially when outfitted with the Sidecar IBM PC compatibility add-on, the Amiga was most commercially successful as a home computer, with a wide range of games and creative software. It also found a niche in video production with the Video Toaster hardware and software, and Amiga's audio hardware made it a popular platform for music tracker software. The processor and memory capacity enabled 3D rendering packages, including LightWave 3D, Imagine, and Traces, a predecessor to Blender.

Poor marketing and the failure of later models to repeat the technological advances of the first systems resulted in Commodore quickly losing market share to the rapidly dropping prices of IBM PC compatibles, which gained 256 color graphics in 1987, as well as the fourth generation of video game consoles.

Commodore ultimately went bankrupt in April 1994 after a version of the Amiga packaged as a game console, the Amiga CD32, failed in the marketplace. Since the demise of Commodore, various groups have marketed successors to the original Amiga line, including Genesi, Eyetech, ACube Systems Srl and A-EON Technology. AmigaOS has influenced replacements, clones, and compatible systems such as MorphOS and AROS. Currently Belgian company Hyperion Entertainment maintains and develops AmigaOS 4, which is an official and direct descendant of AmigaOS 3.1 – the last system made by Commodore for the original Amiga Computers.

Selected article

AmigaOS 4, (abbreviated as OS4 or AOS4), is a line of Amiga operating systems which runs on PowerPC microprocessors. It is mainly based on AmigaOS 3.1 source code developed by Commodore, and partially on version 3.9 developed by Haage & Partner. "The Final Update" (for OS version 4.0) was released on 24 December 2006 (originally released in April 2004) after five years of development by the Belgian company Hyperion Entertainment under license from Amiga, Inc. for AmigaOne registered users. During the five years of development, purchasers of AmigaOne machines could download pre-release versions of AmigaOS 4.0 from Hyperion's repository as long as these were made available.

On 20 December 2006, Amiga, Inc abruptly terminated the contract with Hyperion Entertainment to produce or sell AmigaOS 4. Nevertheless, AmigaOS 4.0 was released commercially for Amigas with PowerUP accelerator cards in November 2007 (having been available only to developers and beta-testers until then). The Italian computer company ACube Systems has announced Sam440ep and Sam440ep-flex motherboards, which are AmigaOS 4 compatible. Also, a third party bootloader, known as the "Moana", was released by Acube on torrent sites; it allows installation of the Sam440ep version of OS4 to Mac Mini G4's. However this is both unofficial and unsupported as of today, and very incomplete, especially regarding drivers. During the judicial procedure (between Hyperion and Amiga, Inc), OS4 was still being developed and distributed. (Full article...)

Selected biography

Jeremy "Jez" San OBE (born 29 March 1966) is an English game programmer and entrepreneur who founded Argonaut Software as a teenager in the 1980s. He is best known for the 1986 Atari ST game Starglider and helping to design the Super FX chip used in Star Fox for the Super NES.

San bought his first computer, a TRS-80, at age twelve. Within a year he taught himself assembly language for several microprocessors.

San founded Argonaut Software in 1982 as a way to get software consulting jobs with large companies. He worked on security systems with British Telecom and Acorn. In 1984, he started developing his first game, Skyline Attack for the Commodore 64, and also co-wrote a book, Quantum Theory, about the Sinclair QL. He became a wizard (admin) at Essex MUD, the world's first multiplayer online role-playing game. (Full article...)

Things to do

  • Create articles: There are many articles that have yet to be started... Pick your favorite and start researching!
  • Find photos for articles: Many Amiga–related articles would be substantially better with the addition of photographs.
  • Expand articles: There are many Amiga stubs which could use extensive updates and development.
  • Find sources: Many poorly sourced articles could use better citations.
  • Wikify: Add {{Portal|Amiga}} to the See also sections of Amiga-related articles.
